This sale is for the vacuum tube only. All test equipment and other junk in the pictures is not part of this listing.
Condition: This was purchased from the Estate of an Electrical Engineer. Date code on the tube is 6126. This comes with a box, but it is not the original box. The base is tight, the pins are straight, the key is in-tact. You can see a little discoloration in the white mica spacer, meaning this tube has seen use but not a whole lot as a w...ell used tube will have plenty of discoloration where the filaments connect to said mica spacer. New tubes are a uniform white in the spacer. The getter flashing has receded a bit, but there is still the vast majority of it. It was hard to photograph due to light bouncing off all the mica spacers at the top of the tube, but it is there.
This vacuum tube was tested on a fully serviced and computer converted Western Electric KS-15874-L1 (made by Hickok for Western Electric).
Important note about the Cardmatic rectifier test circuit. These testers arelimited to 250volts. Rectifier tubes typically run at much higher plate voltages in real-world applications.
Test conditions are found in the final picture.Cardmatic test results:
218ma at 250 volts and 1050 ohms plate circuit resistance
(As a note of reference: Out of the half dozen NOS 422As I sold recently, all but one tested at 218ma which gives me confidence in the quality of WeCo tubes and this tube as well)
No two tube testers will deliver the same results due to the variance in circuits used and/or the measured values of the individual components inside.
Due to the age and nature of vacuum tubes (and having no control over your equipment), they are being soldas-is with no returns. These have beentested to the best of my abilities with equipment that I own, or have accessto. Feel free to PM me to set anappointment to see the item(s) in person, (the transaction will stillbe completed through eBay). Be VERY sure you want this before you buy it as there are no returns accepted.Shipping:
Shipping within the United States is via USPS Priority Mail in a box that will be large to accommodate lots of bubble-wrap to ensure safety of the item. It will be insured and signature will be required (that is what the $6 handling cost covers).
I will only ship internationally, through the US Postal Service via priority mail. It will be insured and signature will be required (that is what the $6 handling cost covers). International buyers are responsible for international postage, import duties, taxes, etc. Please do not ask for other slower / less expensive international shipping options (they take too long), or marking the item as "gift". I will not respond.A personal note on listening. I don't have the most sensitive ear. I am not the person to tell you about thequality or the character of the sound coming from any particular tube or tubeamp. I enjoy the depth and softness ofthe sound that comes out of a tube amp compared to most transistor amps, but Iam incapable of further critique unless the capacitors in the amp are defectiveor a tube is red-plating while in operation and making that nasty screechingnoise ^_^ I do however take care of thethings I come across and try to describe them to the best of my abilities.
